Meinongianism, which describes existence as a property of some but not all entities, was first formulated by [[Alexius Meinong]]. Its main claimassertion is that there are some entities that do not exist, meaning [[objecthood]] is independent of existence. Proposed examples of nonexistent objects are merely possible objects such as flying pigs, as well as fictional and mythical objects like Sherlock Holmes and Zeus. According to this view, these objects are real and have being, even though they do not exist.<ref>{{multiref |1={{harvnb|Casati|Fujikawa|loc=§2a.

For example, there is an object that only has the single property of "being a singer" with no other properties. This means neither the attribute of "wearing a dress" nor the absence of it applies to this object. Meinong also includes impossible objects like round squares in this classification.<ref>{{multiref |1={{harvnb|Nelson|2022|loc=§ 2. Meinongianism}} |2={{harvnb|Casati|Fujikawa|loc=§2a.
